Answer:

Explanation:

A free-body diagram is a sketch of an object of interest with all the surrounding objects stripped away and all of the forces acting on the body shown. The drawing of a free-body diagram is an important step in the solving of mechanics problems since it helps to visualize all the forces acting on a single object. The net external force acting on the object must be obtained in order to apply Newton's Second Law to the motion of the object.

A free-body diagram or isolated-body diagram is useful in problems involving equilibrium of forces.

Free-body diagrams are useful for setting up standard mechanics problems.

poizon [28]

Answer:

1.) 30m/s

2) 5m/s

3) 40Hz

4) 400Hz

5) 300Hz

6) 0.77m

7) 0.386m

8) 0.625m

9) 100m/s

10) 50m/s

Explanation:

The speed of a wave (V) equals :

V = fλ ; where f = frequency, λ = wavelength

1.) f = 100Hz, λ = 0.30m

v = 100 * 0.30 = 30m/s

2) f = 50Hz λ = 0.10m

v = 50 × 0.10 = 5m/s

3) v = 20m/s, λ= 0.5m

f = v / λ

f = 20 / 0.5 = 40Hz

4) v = 80m/s, λ= 0.2m

f = 80/0.2 = 400Hz

5) v = 120m/s, λ = 0.4m

f = 120 / 0.4 = 300Hz

6) v = 340m/s, f = 440Hz

λ = v / f ; 340 / 440 = 0.77m

7) v = 340m/s, f = 880Hz

λ = 340 / 880 = 0.386m

8) v = 250m/s, f = 400

λ = 250 / 400 = 0.625m

9) f = 50Hz, λ = 2m

v = 50 × 2 = 100m/s

10) f = 100Hz, λ = 0.5m

v = 100 × 0.5 = 50m/s

A ticker timer 50dots per second. When a body is pulled by a tap through the timer, the distance between the third and fourth do
Amiraneli [1.4K]

Answer:

Explanation:

Time for one dot = 1 /50 = .02 s

Distance between 3 rd and fourth dot is 3 cm and time taken to travel this distance is .02 s

velocity = 3 cm / .02 = 150 cm /s

Distance between 4 th and 5 th  dot is 4 cm and time taken to travel this distance is .02 s

velocity = 4 cm / .02 = 200 cm /s

change in velocity = 200 cm/s  - 150cm/s = 50 cm /s

Time taken = .02 s

Acceleration = 50 / .02 cm/s²

= 2500 cm/s²
